One of three credit bureaus, Equifax collects that info and more to determine who’s worthy of getting a mortgage, a car loan or a credit card and what kind of interest they’ll pay.

Simply put, the Big 3 know Everything About Us.

Anyway, after visiting www.equifaxsecurity2017.com, we determined that my husband Hank’s info had “likely been compromised.” So he signed up for a year of free credit monitoring on Equifax’s dime.

Since my info was supposedly “not compromised,” I wasn’t eligible. But guess what, I am now. Along with another 2.4 million folks.

The letter I opened Thursday was a “Notice of Data Breach.” It informed me that “On March 1, as a result of ongoing analysis of data stolen in last year’s cybersecurity incident, Equifax … confirmed the identities of approximately 2.4 million U.S. consumers whose partial driver’s license information was impacted in last year’s incident.”

What followed was a convoluted “explanation” of why the latest breach wasn’t discovered sooner. Suffice to say Equifax determined I had joined an undesirable club.

So how “partial” is partial? According to the letter, “The information stolen for the vast majority ... included names, driver’s license numbers and dates of birth, and in a small number of cases also included the addresses and the state of issuance of the driver’s license.”

In other words, plenty to send would-be ID thieves merrily on their way.

While, knock wood, I haven’t had my identity stolen, I previously have had my checking account and several debit cards compromised. The former was a major nightmare and took months to straighten out. I shudder at the thought of something even worse.

So, on Thursday night, I signed up for the free 12 months of identity theft protection and credit monitoring (including internet scanning for my SSN and $1 million in ID theft insurance) that Equifax is offering.

I urge anyone who got a similar letter (I already know of at least two others) to do the same. ASAP.
